The Shifting Sands of Global Order
Foundations of International Relations
What is International Relations?
International relations (IR) is the study of how countries interact. It looks at everything from war and peace to trade and diplomacy. But it's not just about governments. The field also examines the roles of powerful companies, international groups like the United Nations, and even non-governmental organizations (NGOs) that work across borders.
International relations (IR) (occasionally referred to as international studies (IS), although the two terms are not perfectly synonymous) is the study of relationships between countries, including the roles of states, inter-governmental organizations (IGOs), international nongovernmental organizations (INGOs), non-governmental organizations (NGOs) and multinational corporations (MNCs).
Think of it as the big picture of global politics. It tries to answer fundamental questions: Why do nations go to war? How do they cooperate to solve problems like climate change? And who holds power on the world stage?
The World Stage Takes Shape
For much of history, the world was a patchwork of empires, city-states, and shifting territories. The idea of a world made up of independent countries, or states, is relatively new. A major turning point was the Treaty of Westphalia in 1648. This series of peace treaties ended a long and devastating war in Europe. More importantly, it established a new principle for how rulers should interact.
The treaty recognized that rulers had the right to govern their own territory without outside interference. This was the birth of the modern state system.
This new system was built on the idea that states are the primary actors in world affairs. Each state is independent, and no higher authority exists to tell them what to do. This setup has defined international politics for over 350 years.
Core Concepts
To understand IR, you need to know its language. A few key concepts are essential building blocks for almost every theory and discussion in the field.
Sovereignty
noun
The principle that a state has supreme and independent authority over its own territory and population, free from external control.
Sovereignty is the bedrock of the international system. It means that, in theory, every country is the boss within its own borders. The government of France makes laws for France, and the government of Japan makes laws for Japan, and neither can dictate policy to the other.
Anarchy
noun
In international relations, the absence of a central authority or world government to enforce rules and resolve disputes between states.
This term can be misleading. In IR, anarchy does not mean chaos or disorder. It simply means there is no global 911 to call when a country breaks a rule. Each state is responsible for its own security and survival. This condition of self-help profoundly shapes how countries behave.
Finally, there's power. Power is the ability to get others to do what you want. In international relations, power can be military strength, economic influence, or even cultural appeal. A country with a large army has power, but so does a country that controls important trade routes or produces popular movies and technology.
Three Ways to See the World
Scholars use different theories to make sense of the complex world of international relations. Think of them as different pairs of glasses, each highlighting different aspects of reality. The three most common theories are Realism, Liberalism, and Constructivism.
| Theory | Key Idea | Main Actors | Core Motivation |
|---|---|---|---|
| Realism | The world is a competitive, self-help system. | States | Power and Survival |
| Liberalism | Cooperation is possible through institutions and shared values. | States, IGOs, NGOs | Prosperity and Peace |
| Constructivism | Ideas and identities shape interests and behavior. | Individuals, Groups | Shared Norms and Values |
Realism is often seen as the most pessimistic theory. Realists argue that because of anarchy, states are always competing for power to ensure their own survival. They believe conflict is an unavoidable part of international politics. For a realist, alliances are temporary, and international laws are only followed when it serves a state's interest.
For realists, what explains international political phenomena is power and the methods by which states secure it to preserve themselves and their rights of sovereignty.
Liberalism offers a more hopeful view. Liberals agree that the system is anarchic, but they don't think it has to be a constant struggle for survival. They argue that states can cooperate to achieve common goals, like wealth and security. They point to the importance of international institutions (like the World Trade Organization), democracy, and economic interdependence as forces for peace.
Liberals believe that when countries trade with each other and share democratic values, they are less likely to go to war.
Constructivism is different from the other two. It focuses on the power of ideas, norms, and identities. Constructivists argue that the world is not fixed; it is socially constructed. For example, the relationship between the U.S. and the U.K. is very different from the relationship between the U.S. and North Korea, not because of a difference in military power, but because of shared ideas and a history of friendship. Interests are not given; they are shaped by who we think we are and what we believe is right.
These three theories provide powerful tools for analyzing global events. No single one has all the answers, but together they offer a rich understanding of the forces that shape our world.

What is the core principle established by the Treaty of Westphalia in 1648, which became a foundation of the modern international system?
In the context of International Relations, the term "anarchy" refers to the absence of a central world government.
These foundational ideas—sovereignty, anarchy, power, and the major theoretical lenses—are the starting point for exploring the complex dynamics of international relations.
